Dave wrote in to tell us about the kitchen timer he made:

I just wanted to say thank you for putting together such a great site and set of products. I’m a newbie and after about 4 months o studying your articles and using the Diavolino as my development board, was able to make a cool little kitchen timer for my parents this Christmas. I definitely could not have done it without your articles and products.

He documented the project with a series of videos (youtube playlist) showing his progression through building it. Shown above is the breadboarded prototype next to the finished timer.

Thanks for sharing your project photos and videos, Dave!
